The former teen star has become more known for her bizarre behavior.
Amanda Bynes hasn't done any interviews lately.
The former Nickelodeon star reportedly fired her management team last year, ditching her agent, publicist and lawyer when she "retired" from acting.
But the actress has kept the world up-to-date on her life in recent weeks by constantly tweeting personal details about herself.
So it seems only fitting that the 26-year-old former "All That" star would reveal she has an eating disorder on Twitter.
"I'm suing certain blogs and magazines saying I have a mental illness! They take pictures anytime I've gained weight then write a fake story!" she wrote late Thursday. "I have an eating disorder so I have a hard time staying thin."
The candid tweet isn't the first time Bynes has mentioned her weight on her social media account.
“Looking pudgy and I broke my nail,” she wrote in March along with a picture of herself in a tight corset top.
On April 2, Bynes also posted: "Skinny's The F--k."
Similarly, her threat to sue media outlets is not the first of its kind.
Last month, she posted an angry message directed at various news sites.
“I'm suing @usweekly & @perezhilton for continuing to act like I'm doing something wrong by tweeting and walking to photoshoots. F--k you!!!!”she posted on Twitter on Thursday.
Bynes also recently shocked many when she tweeted a series of posts about rapper Drake, saying “I want @drake to murder my vagina.”
But this strange behavior is nothing new for Bynes. Over the past year the star has been reportedly spotted partying in clubs alone and stumbling around the streets of NYC.
Bynes first began acting in commercials at the age of 7 and was thrust into the limelight when she later became one of the stars of Nickelodeon’s comedy show “All That.” She then starred in Nickelodeon’s “The Amanda Show” from 1999-2002. Since then, her acting career has waned, and her last major role was in 2010’s “Easy A.” Before that she appeared in films like “What a Girl Wants” and “Hairspray.”
She tweeted that she is currently working on starting her own fashion line.
